ANNULAR ABSORBER Russian patent published in 2008 - IPC B01D53/02 

FIELD: equipment for realizing adsorption processes in gas (vapor)- adsorbent system.

SUBSTANCE: annular absorber includes cylindrical housing with lid and bottom; said lid and bottom are elliptical ones. Loading and inspection hatches are mounted in lid. Loading hatch is connected with compensating hopper arranged in lid. Union for feeding initial mixture, drying and cooling air is arranged in lower part of housing to which supports are secured for outer and inner perforated cylinders. Discharge of waste adsorbent is realized through discharging hatch mounted in lower part of housing fastened at least in three mounting foots. Union for draining vapor and condensate at desorption and for feeding water is arranged in bottom to which union for draining scrubbed gas and exhaust air and for feeding steam is secured through manifold having two ducts. In one of said ducts there is damper for desorption process having bubbling member of toroidal shape along the whole height of perforated cylinders. Union for safety valve is mounted in upper part of housing. Perforation factor of toroidal surface of bubbling member is in range of optimal values K = 0.5 - 0.9.

EFFECT: improved gas scrubbing degree of gas flow from target component and dust due to increased contact area of adsorbent and target component.
